Suppose that you have a square pyramid like the one pictured. Which plane section will produce a trapezoid? Question 4 options: A) Cutting off one of the bottom corners B) A cut parallel to the vertical axis, directly through the vertical axis C) A cross section cut parallel with the bottom D) A cut parallel to the vertical axis, but off the vertical axis
When you have a square pyramid, the plane section that will produce a trapezoid is B. A cut parallel to the vertical axis, directly through the vertical axis
What is a square pyramid?It is defined in geometry as a shape with a square base with equal side lengths and all of the square's joints at the top that are perpendicular to the center of the square.
Geometry, as we know, is the branch of mathematics concerned with the size, shape, and orientation of two-dimensional figures. A trapezoid, also known as a trapezium, is a closed, flat shape with four straight sides and one pair of parallel sides.
It's parallel sides are known as the bases, and its non-parallel sides are known as the legs. A trapezoid can have parallel legs as well.
In this case, the cut parallel to the vertical axis, directly through the vertical axis will produce the trapezoid.
In conclusion, the correct option is B.

What is the y-intercept of a line that has a slope of 2 and ( - 2, 3 ) is a point on the line?
The y-intercept of the line will be equal to 7.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that a line that has a slope of 2 and ( - 2, 3 ). The y-intercept of the line will be calculated as,

ADC ~ CDB by the AA triangle similarly theorem. what is the measure of AC? Round to nearest 10th
The measure of side AC in the triangle is 2.7 m
Calculating measures of sides in similar trianglesFrom the question, we are to determine the measure of AC
From the given information, we have that ΔADC is similar to ΔCDB
Thus,
We can write that
|DC| / |DB| = |AC| / |CB|
From the diagram,
|DC| = 5.5 m
|DB| = 6.3 m
|AC| = h
|CB| = 3.1 m
Then,
5.5 / 6.3 = h / 3.1
∴ h = (5.5 × 3.1) / 6.3
h = 17.05 / 6.3
h = 2.70635 m
h ≈ 2.7 m
Hence,
The length of AC is 2.7 m

Answer:
positive 3
Step-by-step explanation:
Steps:
1. first you must get y by itself/isolate it to one side of the equation to get it in the format of y = mx + b
-3x + 2y = 6
+3x +3x add 3x to both sides to get 2y by itself
____________
2y = 3x + 6 -3x+3x cancels out and becomes 0
-------------------------
2 divides both sides by 2 to get y by itself
y = (3/2)x + 3
2. Looking at the equation, we know that 3 is the y-intercept because the "b" in the slope-intercept equation is always the y-intercept.
Sheila is making accessories for the soccer team. She uses 784.96 inches of fabric on headbands for 28 players and 4 coaches. She also uses 238.28 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
Answer: 3.28 inches
Step-by-step explanation:
Fabric used for players and coaches is 776.32 inches.
Number of players is 29 and coaches is 3
So fabric used for each player and coach for the headbands is
776.32/29+3 = 24.26 inches
So, for the players 24.26 of fabric will be used for the headbands.
Total fabric used for the wristbands is 247.66 inches
Fabric used for the wristband is
247.66/29 = 8.54 inches
So, total amount of fabric used by Shelia for the wristband and headband is 24.26 + 8.54 = 32.8 inches.
The screenshot included A crate of medicine with a density of 2050 kilograms per cubic meter that will be shipped from England to the U.S. What is the crate's density in pounds per cubic foot?
The crate's density in pounds per cubic foot?
What is the crate's density in pounds per cubic foot?Since the crate of medicine with a density of 2050 kilograms per cubic meter will be shipped from England to the U.S, we require its density in pounds per cubic foot.
To do this, we convert the density in kilograms per cubic foot to pounds per cubic foot by using the ratios of conversion given
Since the density of the crate in kilograms per cubic meter is
2050 kg/m³, using the conversion ratios, we have
2050 kg/m³ = 2050 kg/m³ × 1 m³/35.3 ft³ × 2.2 lb/kg
= 4510 lb/m³ × 1 m³/35.3 ft³
= 127.76 lb/ft³

Over three days, Molly earns $2,568 for a local charity. On the first day, she earns twice as much as she earns on the second day. On the third day, she earns three times as much as the second day. How much does she earn on the first day?
If on the third day, she earns three times as much as the second day. The amount that she earn on the first day is $856.
How to find the amount earned?Let a = Amount earned on the first day
Let b = Amount earned on the second day
Let c = amount earned on the third day
Let a + b + c =2568,
Hence,
2b + b +3b =2568
6b =2568
b =2568/6
b =428 second day
So,
a = 2b
a =2(428)
a =856 first day
Thus
c = 3b where b = 428
c=3(428)
c=1284 third day

Both function in item I is decreasing, and the function in item II is increasing.
What is function?
A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, co-domain, and domain.
What is domain?
The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.
What is range?
The difference between the lowest and highest values in a list or set is known as the range. Put all the numbers in order before determining the range. The lowest number should then be subtracted from the highest. The range of the list is provided in the response.
1) As shown in the I that the function is in 3rd quadrant so thats why it decreases.
2)As show in II figure if ;

Which points are on the axes 5 units from the origin
Answer:
E and X
Step-by-step explanation:
look for the 6 then behind it
Answer:
X and E
Step-by-step explanation:
"axes" is the plural of axis. The x-axis is the flat line marked with numbers and arrows at the ends. Its labelled x on the right side.
The y-axis is the up-and-down line marked with numbers and arrows at the ends, labelled y at the top.
The origin is where the two axes cross.
Points J, E, X and P are all on the axes. But X and E are 5 units from the origin (where the lines cross) J and P are 9 units from the origin.
2, 6 and 10 were labelled on the axes, but each tick mark is an evenly spaced amount. So the 5 was unlabelled, but it is understood to be 5. See image.

What is linear equation ?A straight line equation and equations with a maximum order of one are referred to as "linear equations." The formula for the linear equation can be written as Y = mx + b, where m is the slope of the line, b is the y-intercept, and x and y are the variables. Slopes tell us the direction and steepness of a line. The value of y when x is 0 is referred to as the y-intercept because (0,y) is the point where the line crosses the y-axis.
CalculationLet's say the number of calls on the second night was x.
The first evening was then x+7.

The horsepower (hp) that a shaft can safely transmit varies jointly with its speed (in revolutions per minute (rpm))
and the cube of the diameter. If the shaft of a certain material 2 inches in diamter can transmit 16 hp at 120 rpm,
what must the diameter be in order to transmit 30 hp at 150 rpm?
The Diameter of the cube would be 3 inches
What is Variation?
A variation is a relationship that exists between a set of values for one variable and a set of values for other variables.
Solution:
We know that,
Horse Power is directly proportional to RPM * Diameter
So, we can write
Horse Power = k * RPM * Diameter
here, k is any constant
From the first case given, we can find the value of k
16 = k * 2 * 120
k = 1/15
Putting the value of k in second case,
